FIELD OF THE INVENTION

The present invention relates to a sport climbing equipment, and more particularly to a climbing assisting equipment.

BACKGROUND OF THE INVENTION

Climbing, which is a prevalent activity suitable for all ages, is helpful for improving body softness, coordination, strength, attention, enterprise, confidence, and equilibratory sense. Sport climbing, as compared with traditional climbing, is safer and more accessible and becomes a mainstream climbing activity as the traditional climbing is dangerous and difficult. In areas or countries such as Europe, USA, and Canada, the artificial climbing wall is widely distributed indoors and outdoors.

When doing sport climbing on artificial climbing wall, a climber is usually fastened with a rope. The rope is used for preventing the climber from falling down and for helping the climber to be grounding after the climbing, but the climber has to operate the retracting and releasing of the rope during the climbing. For a climber who only wants to enjoy the pleasure of the climbing or is a beginner, it is a cumbersome work for the climber to operate the rope and spends his/her strength and spirit. Therefore, it will thus reduce his/her interest.

In view of the reason, there is a sport climbing equipment used for replacing manpower in rope release. However, since a conventional sport climbing equipment in a prior art always releases the rope in a constant speed regardless of an instantaneous falling speed or a descending speed of the climber, it thus tends to cause the climber be hurt, and it finally still needs an operator to handle the sport climbing equipment.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Please refer to FIGS. 1 to 3, FIG. 1 is a schematic diagram of a climbing assisting equipment according to an embodiment of the present invention; FIG. 2 is a schematic diagram of the climbing assisting equipment in a situation where a climber is climbing up according to the embodiment of the present invention; and FIG. 3 is a schematic diagram of a climbing assisting equipment in a situation where a climber is descending according to another embodiment of the present invention.

As shown in FIGS. 1 to 3, a climbing assisting equipment 100 according to an embodiment of the present invention includes a rope transmitting device 1, a slow-descending device 2, and a regulating device 3.

The rope transmitting device 1 includes a rope member 11 and a rope reel member 12. The rope reel member 12 is connected with the rope member 11 to retract or release the rope member 11. In this embodiment, the rope reel member 12 includes a case body 120, a rotary shaft 121, and two side wall portions 122 a and 122 b. The rotary shaft 121 is supported by bearings 121 a and 121 b in the case body 120 for being rotated, the rope member 11 is connected to the rotary shaft 121 to thus be retracted/released to/from the rotary shaft 121 when the rotary shaft 121 is being rotated. The side wall portions 122 a and 122 b are provided at both lateral sides of the rope member 11 to prevent rope member 11 from disordering during being retracted/released and to maintain the rope member 11 to be operated between the side wall portions 122 a and 122 b.

The slow-descending device 2 includes a transmission member 21, a generator 22, and a generator load 23. The transmission member 21 is connected between the rope reel member 12 and the generator 22. The transmission member 21 in this embodiment include a shaft gear 211 and a generator gear 212, wherein the shaft gear 211 is connected with the rotary shaft 121, the generator gear 212 is connected with the generator 22, and shaft gear 211 is engaged with the generator gear 212 so that the generator 22 can be driven by the rope reel member 12.

The generator 22 is provided with a one-way input shaft 221 connected to shaft gear 212. When the rope member 11 is pulled down from the rope reel member 12, the one-way input shaft 221 is turned in a positive direction to drive the generator 22 to generate electrical power to the generator load 23. On the contrary, when the rope member 11 is retracted by the rope reel member 12, the one-way input shaft 221 is turned in a reverse direction without generating electrical power by the generator 22.

In the case that the generator load 23 has a constant load value, higher the rotation speed of the generator 22 is, the resistant moment (moment force) to against the generator 22 is larger. The resistant moment will suppress the rotation of the one-way input shaft 221 to thus reduce the descending speed of the rope member 11 via the transmission member 21.

With above structure, when the rope member 11 is retracted by the rope reel member 12, the rotary shaft 121 drives the transmission member 21 to turn the one-way input shaft 221 being rotated in a reverse direction so that the generator is idle without any rotation. When a climber is falling down or is descending, the rope member 11 is pulled down from the rope reel member 12 and the one-way input shaft 211 of the generator 22 is turned in a positive direction by the rope reel member 12 via the transmission member 21, to thus drive the generator 22 to generate electrical power to the generator load 23. And, higher the descending speed is, the rotation speed of the generator 22 is increased, and thus the larger resistant moment will be generated. The resistant moment will reduce the descending speed of the rope member 11, so that the descending speed of the climber is slowed down. Then, the slow down of the climber will decrease the resistant moment. Finally, when the terminal descending speed as a constant descending value when the descending moment and the resistant moment is balanced in final. Since the descending speed is slowed down to reach the final constant descending value, the climber will not feel uncomfortable during descending.

The regulating device 3 includes a weight sensor 31 and a load adjustment 32. The weight sensor 31 is provided to sense the weight of a climber. The weight sensor 31 in this embodiment is an electronic weighing scale means disposed in the ground for sensing an original weight W of a climber C before the climber C fastens the rope member 11. The load adjustment 32 is connected between the weight sensor 31 and the generator load 23 and is used for receiving the weight W of the climber C from the weight sensor 31 and for adjusting the generator load 23 according to the weight W. The load adjustment 32 usually adjusts the generator load 23 to be in proportion to the weight W of the climber C.

Based on the reason that larger generator load 23 is, the resistant moment to the generator 22 is increased, therefore a desired deceleration speed for different weight climbers can be calibrated and adjusted by means of adjusting the generator load 23 according to the weight W of the climber C.

Please refer to FIGS. 4 and 5, FIG. 4 is a schematic diagram of a climbing assisting equipment in a situation where a climber is climbing up according to another embodiment of the present invention; and FIG. 5 is a schematic diagram of the climbing assisting equipment in a situation where a climber is descending according to another embodiment of the present invention. The elements of climbing assisting equipment 100 a in this embodiment are similar to those in the above embodiment. The same elements in this embodiment are labeled with the same reference numbers as in the above embodiment, and the detail descriptions for the same elements will be omitted as appropriate.

In this embodiment, the climbing assisting equipment 100 a further includes a suspension device 4. The suspension device 4 is connected between the rope transmitting device 1 and a fixed object F, such that the rope transmitting device 1 has a displacement H generated by a loading on the rope member 11. The suspension device 4 in this embodiment includes a receiving member 41 and a resilience member 42. The receiving member 41 is connected to the rope transmitting device 1, the resilience member 42 is connected resiliently between the fixed object F and the receiving member 41 to hold the rope transmitting device 1 and to be lengthened/shortened according to the loading on the rope member 11. In such structure, when a certain loading is provided on the rope member 11, the rope transmitting device 1 is pulled by a tension force generated by the loading to move downward. A relation between the displacement H and the tension force can be determined by an elastic coefficient of the resilience member 42.

Further, a transmission member 21 a of the slow-descending device 2 in this embodiment is a clutch member. The clutch member includes a first gear 213 connected with the rope reel member 12 and a second gear 214 connected with the generator 22. The first gear 213 is provided to move along with the rope transmitting device 1. When the displacement H is larger than the reference displacement, the first gear 213 is moved to engage with the second gear 214 such that the rope reel member 12 can drive the generator 22 to generate electrical power. On the contrary, when the displacement H is not larger than the reference displacement, the first gear 213 is separated from the second gear 214 to thus release the rope reel member 12 from the generator 22.

With above structure, when the rope member 11 is retracted by the rope reel member 12, the loading on the rope member 11 is relatively small, such that the clutch member is moved to release the rope reel member 12 from the generator 22. When the climber is descending, the loading on the rope member 11 is relatively large due to the weight of the climber C applied to the rope member 11, such that the clutch member is moved to make the generator 22 to be driven by the rope reel member 12 to generate electrical power to the generator load 23 to thus reduce the descending speed of the rope member 11.
